Abstract
A belt tensioning system includes a stretch belt rotationally connected to a crankshaft pulley and an accessory pulley, and a tensioning device including a pivoting arm having a tensioning pulley coupled thereto and an arm stop positioned in a path of the pivoting arm to limit the rotation of the pivoting arm. Additionally, the tensioning device does not include a spring tensioner and is configurable in a tensioned configuration and an un-tensioned configuration.
Claims20
A belt tensioning system comprising:
- a stretch belt rotationally connected to a crankshaft pulley and an accessory pulley;
- and
- a tensioning device including a pivoting arm having a tensioning pulley coupled thereto and an arm stop positioned in a path of the pivoting arm to limit rotation of the pivoting arm, the arm stop comprising a removably coupled stop plate, wherein the stop plate has an outer surface in direct face sharing contact with a side of the pivoting arm when the tensioning device is in a tensioned configuration;
- the tensioning device not including a spring tensioner and being configurable in both the tensioned and an un-tensioned configuration.

A belt tensioning system in an engine, comprising:
- a stretch belt rotationally connected to a crankshaft pulley and an accessory pulley;
- and
- a tensioning device including a pivoting arm having a tensioning pulley coupled thereto and an arm stop positioned in a rotational path of the pivoting arm to limit rotation of the pivoting arm, the arm stop comprising a removably coupled stop plate, wherein the stop plate has an outer surface in direct face sharing contact with a side of the pivoting arm when the tensioning device is in a tensioned configuration;
- where the tensioning device does not include a spring tensioner;
- where when the pivoting arm is in the tensioned configuration the tensioning pulley is in rotational contact with the stretch belt and exerting tension thereon;
- and
- where when the pivoting arm is in an un-tensioned configuration the tensioning pulley is spaced away from the stretch belt.
